This invention relates to improvements'in' disc plows, and has for; its object to provide means for spacing the discs ona supporting shaft in such away thatthe spaces between the discs may be varied; For the'purpose of eifecting this variation. and adjustment there isprovided between the adjacent disos a pluvrality of cooperating spacing elements,

' adapted to be used in connection with each z other in such a way that by the adjustment of these elements the spaces between the discs may e varied; In the present instance the is accomplished by means of a barrel or spool member' adapted to-engage atone end with I one of the faces ofza disc, while on the other end'of the barrel member there is a cupshaped member adapted to cooperate there- 7 with in such a way as to provide two adjustments between adjacent discs. The cupbarrel member may-be composed of two parts,

easily detachable one from the other, with a head on each end for engagement with dif- ,ferent sides of discs, and cooperating with either of these heads is a cup-shaped member adapted to be used in connection with the double headed barrel or spoolmember for forming an additional spacing element coo crating with thisspool or barrel member. n this form the cup-shaped member may co operate with only one part of the barrel member so that less space may be provided *between two adjacent discs I I The purpose of having and providing this adjustment between discs is that the soil may be either broken in large chunks or may be more finely pulverized, owing'to the .condition of the soil and the ends desired or required. ,Forearly breaking of land it is desirable to have the discs spacedsome distance apart, while in later breakingv of the soil,

where it is desired-to more finely divide and pulverize the soil, it is necessary that'the discs be closer. i I f I These and other advantages will appear from the following description taken in connection with the drawings; I i

Referring to the drawings;

,Figure 1 is a. top plan'viewjof a 'dj fi ld c or harrow supported the usualfra'rne and wheels. j a i Figure 2 1s a longitu inal sectional view through a series of discs mounted on thesup Y porting shaft, showing one form of g m means and one adjustmentof this form."

v Figure 3 is. a sectional view similar to liigure 2 but showing the spacers in a different arrangement from that shown inFigure 2. Figure 4 is amodified form of spacer; Figure is a view similar to Figure 4 but showing in conjunction 'with the 1 spacer shown in Figure 4 a cup-shaped member to 1 increase the spacing effect of the spacer.

' Figure 6 is a longitudinal section through the thrust bearing v Figure 7 isa cross section on the line 7 7 of Figure 1.

In Figure 1 there is shown a form of disc plow or harrow, the details ofwhich it is unnecessary to describe. usualframe is found for supporting the discs and the disc shaft. This fram i indicated by the numeral 1 and has attached thereto and'supported thereby the usual gang of discs 2.- Extending rearwardly from one end of the frame is an angular extension 3 which serves as a thrust bearing for one end of the shaft that carries the discs. The frame is supported by the usual rear Wheel i and front wheels 5 and 6. j I

Suitably attached to the angular extension is a bearing cup 7 shown in Figure 6.,. This cupis supported by a bracket 8 forming part of the frame 1. "The cup is supported and heldto the bracket by means of bolts 9. on one end of a longitudinal shaft is a bearing In thisform the .lit a corresponding face of a disc.

head 10 adapted to fit within the cup 7 so as to fully and completely support one end of a shaft 11 which supports the discs, and hold the shaft against end thrust. This shaft is square for supporting the discs. tlne end of the shaft is threaded to engage a threaded socket in the bearing head 10. While the cup 7 supports one end of the shaft, the other end and the parts of the shaft intermediate the ends are supported by arms 12, each arm being attached at one end to the frame and having in the other end a bearing in which the shaft rotates. These arms extend from a part of the frame between certain of the discs. The bearings on the ends of the arms are indicated by the numeral 18 and are illustrated in Figure 7.

While one end of the shaft and its bearing head are supported by the cup member 7, the other end has a nut 14 thereon for the purpose of holding the parts in relation to each other and for holding the discs and spacers on the shaft. The individual discs are indicated by the numeral 15 and are the usual dish-shaped discs found in farm implements of this kind. While these discs are shown to be of this shape the spacers here provided may be used with any form of disc. the form here being used by way of illustration only.

In order to provide for convenient adjustment between the discs spool or barrel members 16 are provided. These spool or barrel members have on one end a flange which provides a concave seat 17 to receive a CODVGX side of a disc. The other end of the barrel or spool member is not enlarged and is adapted to receive and support thereon a cup-shaped member 18. The bottom of the cup member is hollowed out, as indicated by the numeral 1.9. The outer edges of the bottom part of the cup member are convex as indicated by the numeral 20, to engage and fit in a concave side of a disc. The other or top end 21 of the cup member has its walls convex in shape By this means the barrel member and the cup-shaped member may be arranged as shown in Figure 2, to provide one adjustment between the discs. By inverting the relative positions of the cup and the barrel member the space between the discs may be increased ant. made larger, as indicated in Figure 3. In Figure 3 the hollowed-out bottom of th cup rests onthe small end of the barrel member.

In the form shown in Figure .l the spacer member is composed of a barrel or spool member formed in two parts. On each end of his spacer member there is a flange. In one of these disc ends there is formed a concave seat 23 to receive a convex side of a disc. @ne part of this barrel or spacer member is indicated by the numeral 22 and has the central end thereof a socket 24 .to receive projection on the other part of the barrel member 25. These two parts constitute spacer as shown in Figure 4. The end of the spacer remote from the concave part 23 is convex, as indicated. by the numeral 26. The two ends are similarly formed and similarly shaped, with the exception that one end has a concave seat therein while the other one has a. convex seat to receive and accommodate different faces of the discs.

In Figure 5 a form of spacer similar to shown in Figure 4 is shown. However. there associated with the barrel member a cupshaped member similar o that shown in con nection with Figures 2 and 3. The cup member here hown is indicated by the same erence character. In the cup member shown in Figure 5 the bottom part of the cup is pro- 'vided with a concave seat to engage the convex end of the barrel spaced member. The other or upper end of the cup member is con- .vei: to engage the concave face of disc.

As shown in this figure, the cup member placed between the convex end of the spa er barrel member and a disc, but this cup 1118111- ber could as readily be placed betwee the other end of the barrel member and the disc engaged thereby. This would merely volve the shifting of the cu member T21 one ens of the barrel member to the other. lhe. on member has its ends so shaped that can be fitted against either side f a disc and it may engage either end of-the bar: member. It is also possible in the form shown in Figure 5 to remove the part 25, in which case the hollowed-out portifn in the bottom of the cup member will fit e small end of the part 22 so that there provided a still smaller space between the two adjacent discs. By proper arrangement the 3. :rts shown n Figure 5, three adjustments may be between two adjacent In one of these adjust: 1 three of the parts are used. shown igure 5. In another one of these adjustments the parts are such as shown in Figure l. If tne part 25 were omitted and the cup member fitted on the small end of the part 22 still a third adjustment would be effected. lit is apparent from an examination of the figures shown here that applicant has provided a means by which the adjacent discs of disc harrow or plow may be adjusted with relation to each other so that the space between the two adjacent discs may barelatively great or relatively small.

By the use 0 the spacing means here DIX videc the space between adjacent discs mav be varied two or more inches. fill that is necessary to properly space and ainst the discs is the nut 14 on the end of the shaft be removed so that the discs may be slipped off and replaced. wi h the proper spacing between them. The bearings on the ends of the arms 12 are such that the shaft can be readily removed therefrom for disc-adjusting purposes. lt it also obvious from an examinati on of Figure 6 that the bearing head 10 constitutes a seat for the disc on the end of the adjacent discs for adjusting the relative posi tion of one to the other. While these spacers are intended to be used for the purpose of equally spacing the discs one from the other they may be used, if it should be found necessary, to space the discs one from the other at different spaces so that the spaces between the discs may be varied, if such were desired.
